The requirement for a grounding terminal is independent of the requirement for the current load.
You could, in theory, have a double-insulated or ground-fault device with 1,500 watts and not require any grounding conductor at all.

Whether a device requires a 3-prong power cord depends on its design and electrical requirements. The wattage alone does not determine this. However, devices that consume more than 1000 watts typically require a 3-prong power cord for safety reasons. For devices with lower wattage, it is best to consult the manufacturer's specifications or the device's user manual to determine the necessary power cord.

Does electric work when power cord is not attached to device?
NO.It can't.
A flexible cord connection is made directly to the load end terminals of a busway plug-in device. The maximum length of this cord to a tension take-up device is?
the length of the cord or cable from a busway plug-in device to a suitable tension take-up support device shall not exceed 6 ft.
What is a IEC 60320 Power cord?
The IEC 603020 cord is a standard power cord that can be used on many differant devices. They are also used to replace a lost or damaged cord. Power cords are not very costly.
Does the bowflex treadclimber have a electrical cord?
Yes the Bowflex Treadclimber has a power cord
Does a long extension cord draw more power than a short extension cord?
No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.
Can you replace a 7 amp 125 volt power cord with a 3 amp 125 volt power cord?
If the device you are powering requires 7 amps of power, then no. You will need to find a replacement cord with 7 amps. Check the power input requirements of the device to find out.
Does electric work when power cord is not attached to device?
NO.It can't.
What device is used to charge a hand held computer?
the answer choices are .. extension cord, power adapter, data cable, or telephone cord
What is the definition of a power tool?
A power cord is an electrical cord that provides power to a wide variety of electrical items. Any product that is run by electricity would require a power cord in order to plug into an electrical outlet which will then provide power for the product to work.
What company makes the best power supply cord for laptops?
The best power supply cord for laptops is the ZIPLINQ Retractable. You can purchase the cord at your local Wal-Mart for under $10. The ZIPLINQ is a 5’ universal cord, best used on laptops that require a ‘Mickey Mouse’ style power cord. It has high user reviews and is a top choice for computer tech’s.
Why some appliances perform quite when long extension cord are used?
An appliance which does not use much current will perform satisfactorily with a long extension cord. Any device which uses a lot of power (space heater, large power tools) will not perform well on a long ext cord unless the cord is large enough and rated to carry the required power.
Usb devices get there power from?
The USB hub can supply power through the USB cable itself. Sometimes, the device requires more power than the hub can provide. In that case, there is usually a power adapter to an outlet in your house to power it and a USB cable to make the connection. Also USB cord supplies power to devices that require less than 500mA(milliamperes) current.
A USB device has exceeded the power limits of its hub port?
Sometimes USB devices will display a warning that they have exceeded the power limits of the hub port. This means that the port cannot keep up with the power demands of the device. To fix the problem, either switch ports, or connect the device to an outlet cord.
Why do my usb cords heat up when plugged in?
USB cables can carry both data and power. If the device attached by the USB cord is drawing a lot of power this could possibly cause your cord to heat up, especially if there were a fault in the cord itself. The best way to test the cord is to simply replace it with another cord you think is good and see if it heats up also.
Why are some power cords thicker than others?
It has to do with current requirements of whatever you plug into it. Things that heat up require a thicker cord to transport the current. A thinner cord may overheat.
How much energy does a cable box use?
The answer to this kind of question is almost always printed on the back of the device near the power cord. Look for it.
Is it better to use laptop battery or power cord?
